Description

The present invention relates to a magnifying glass for a mobile information terminal capable of magnifying and viewing a display screen of a mobile information terminal such as a smartphone.

Smartphones, which are mobile information terminals, are about 7 inches in size, even though their display screens have become larger in recent years. On the other hand, smartphones that can be operated intuitively on the display screen are gradually becoming widespread among the elderly.

However, even the enlarged display screen is not yet large enough for the elderly. In particular, many people wear reading glasses when typing letters in emails. Therefore, for example, the "image magnifying lens for a mobile phone" described in Patent Document 1 has been proposed as a display screen that can be magnified and viewed.

This image magnifying lens for mobile phones has a structure in which a clip is rotatably attached to the lower end of a support, a lens frame is rotatably attached to the upper end of a support, and a magnifying lens is fitted to the lens frame. By attaching it to a mobile phone via a clip, the display screen can be magnified by a magnifying lens to see clear images and characters.

Japanese Unexamined Patent Publication No. 2013-70352

However, the "magnifying lens for mobile phones" disclosed in Patent Document 1 has the following problems. That is, since the display having a smooth surface is attached so as to be sandwiched between the clips, there is a problem that the clips are slippery and easy to move, and the positions of the columns and the magnifying lens are difficult to stabilize.

For this reason, even if the position of the magnifying lens with respect to the display screen is properly determined at the beginning, it may be misaligned during use or the clip may come off from the display, which makes it difficult to use. In addition, there is also a problem that so-called small scratches such as scratches are easily attached to the portion of the display where the clip hits.

Furthermore, since the magnifying lens is always exposed even when not in use, it is easily damaged by contact with other places. To prevent this, for example, prepare a bag to store it. Was needed.

The present invention has been devised in view of the above points, and can stably maintain the positional relationship between the magnifying lens and the mobile information terminal when the display screen of the mobile information terminal is magnified and viewed. It is an object of the present invention to provide a magnifying glass for a mobile information terminal, which can prevent a magnifying lens from coming into contact with another place and being damaged when not in use.

[1] In order to achieve the above object, the magnifying glass for a personal digital assistant according to the present invention is attached to a substrate having a predetermined shape and one end of the upper surface of the substrate so that the angle can be adjusted with respect to the substrate. At the other end of the upper surface of the magnifying glass and the substrate, a storage space for accommodating the magnifying glass can be formed between the magnifying glass and the upper surface, and the base end portion thereof can be formed in a shape capable of leaning a mobile information terminal. It includes a first variable plate that is connected.

A magnifying glass for a personal digital assistant glass has a magnifying lens attached to one end of the upper surface of the substrate so that the angle can be adjusted with respect to the substrate. It can be adjusted to a suitable angle.

Further, since the base end portion of the first variable plate is connected to the other end of the upper surface of the substrate so as to form an accommodation space for accommodating the magnifying lens between the first variable plate and the upper surface, the first variable plate can be used. A magnifying lens can be housed inside the covered storage space. As a result, it is possible to prevent the magnifying lens from being damaged by contact with another place.

Moreover, since the base end portion is connected so that the first variable plate can be formed in a shape that allows the mobile information terminal to be leaned against the other end of the upper surface of the substrate, the portable information terminal is connected to the substrate. You can stand the screen at an appropriate angle by leaning against it.

[2] The magnifying glass for a mobile information terminal according to the present invention is a second variable plate to which a base end portion thereof is connected so that a support portion for raising the substrate can be formed at one end portion of the lower surface of the substrate. It can also be configured to include.

In this case, since the base end portion of the second variable plate is connected to one end portion of the lower surface of the substrate so that a support portion for raising the substrate can be formed, when the second variable plate is placed on the upper surface of the desk top plate or the like. The support portion allows the substrate to be tilted so as to be tilted up toward the mounting portion of the magnifying lens.

As a result, when the user sees from a relatively high position, for example, the magnifying lens and the portable information terminal on the other side of the magnifying lens are likely to fit in the vertical viewing angle of the user. Therefore, the user can magnify and view the screen of the mobile information terminal without taking an unreasonable posture such as lowering his head and looking into the magnifying lens.

[3] The magnifying glass for a mobile information terminal according to the present invention has the first variable plate or the second variable plate, or the first variable plate and the second variable plate have a flat plate shape or a tubular shape. Alternatively, each form can be deformed into a bent plate shape, and each form can be maintained.

In this case, by making the first variable plate and the second variable plate flat, the thickness of the magnifying glass for a personal digital assistant can be made thin, and the folded form can be made into a compact design. Can contribute to doing.

Further, the tubular shape makes the shape suitable for leaning a mobile information terminal or raising the substrate. Further, by making the shape of a bent plate, when the other end of the substrate is used as a fulcrum, the inclination can be adjusted by changing the position of the bent portion.

[4] The magnifying glass for a mobile information terminal according to the present invention may have a configuration in which the first variable plate or the second variable plate has a polygonal tubular shape.

In this case, since the tubular shape of the variable plate is a polygonal cylinder, the variable plates are formed into tubular or curved plate shapes, and when the shape is maintained, the flat plates constituting the polygonal cylinder are used together. By combining the above, the joint surfaces are less likely to shift from each other, and the choices of joining means that can be adopted are increased, so that the form can be easily maintained.

[5] The magnifying glass for a mobile information terminal according to the present invention has a non-slip feature for stopping the magnifying glass for a mobile information terminal mounted on the upper surface of the substrate near the connection portion of the first variable plate. It can also be configured to be provided.

In this case, the first variable plate is formed in a shape that allows the mobile information terminal to be leaned against, and when the mobile information terminal is leaned against and placed on the non-slip, the portion in contact with the non-slip is at that position. It stops at and the position does not shift easily. As a result, the position of the leaning mobile information terminal and the inclination of the screen can be maintained in the set state.

[6] In the magnifying glass for a mobile information terminal according to the present invention, the magnifying lens can be adjusted to the angle at the time of folding and the angle at the time of use, and the angle at the time of use can be set to a plurality of angles different from each other. It can also have a certain configuration.

In this case, when the magnifying glass for the mobile information terminal is folded, the magnifying lens can be adjusted to the angle at the time of folding. Further, when using the magnifying glass for a mobile information terminal, the magnifying lens can be adjusted to the angle at the time of use. In this way, the angle of the magnifying lens can be adjusted according to the folded state and the used state.

Further, the magnifying lens can be set to a plurality of angles different from each other in the usage state. Since there are multiple set angles when using the magnifying lens, the screen is easy to see, for example, when the mobile information terminal is leaned against the first variable plate, the angle of the magnifying lens is adjusted to be parallel to the screen of the mobile information terminal. It becomes easier to adjust to the angle.

[7] The magnifying glass for a personal digital assistant according to the present invention may have a configuration in which the magnifying lens is a flat lens.

In this case, if the magnifying lens is a flat lens, the lens becomes flat and thin, so that the accommodation space formed by the first variable plate between the magnifying lens and the substrate can be thinned (or narrowed). , The magnifying lens can be accommodated compactly.

INDUSTRIAL APPLICABILITY According to the present invention, the positional relationship between the magnifying lens and the personal digital assistant can be stably maintained when the display screen of the mobile information terminal is magnified, and the magnifying lens comes into contact with another place when not in use. It is possible to provide a magnifying glass for a mobile information terminal that can be suppressed from being damaged.

The structure for rotatably connecting the lens fixing plate 12 and the support leg plate 13 is a resin sheet 131 in which each plate body 130 is stretched on the surface, similarly to the upper variable plate 3 and the lower variable plate 4 described later. A V-shaped groove 132 extending to the opposite side of the resin sheet 131 is provided at the boundary portion of each plate body 130 (see FIG. 7).

The magnifying lens 2 is a rectangular, flat plate-shaped flat lens. In this embodiment, a Fresnel lens having a size of 140 mm in length and 250 mm in width is used. The magnifying lens is not limited to a Fresnel lens as long as the object can be magnified and viewed at a required magnification, and a lens having another structure such as a thin convex lens can be adopted.

Further, the shape (outer shape) of the magnifying lens 2 is not limited to a rectangle, and other polygons, a circle, an ellipse, or the like can be adopted. For example, all or one of the corners of various polygons can be adopted. It is also possible to adopt a portion having a rounded arc shape or the like.

At both ends of the upper variable plate 3 in the longitudinal direction, reinforcing sheets 39 having a required width are stretched on the resin sheet 32 side over the entire length of the upper variable plate 3 in the lateral direction. When the upper variable plate 3 is extended into a flat plate shape, the upper variable plate 3 has a rectangular shape having substantially the same size as the substrate 1 so as to cover the upper surface 10 of the substrate 1 (see FIGS. 6 and 7).

Then, first, the magnifying lens 2 is tilted so as to be close to the substrate 1, and while the upper variable plate 3 is extended, each magnet 35 of the thin plate 31b is placed on each magnet 16 at the base of the magnifying lens 2 so as to cover the magnifying lens 2. The upper variable plate 3 can be substantially maintained in a flat plate state (see FIGS. 6 and 7). Further, as a result, an accommodation space 15 for accommodating the magnifying lens 2 can be formed between the substrate 1 and the upper variable plate 3.

When the upper variable plate 3 of the V-shaped groove 33 has a flat plate shape, the internal angle is about 70 ° in the present embodiment. As shown in FIGS. 1 to 3, when the upper variable plate 3 is rolled up, the thin plates 31a and 31b are overlapped, and the magnets 34 and 35 are magnetized to form a polygonal cylinder, a seven-sided cylinder is formed. The number of angles formed when the upper variable plate 3 is rounded is not limited to the seven corners, and the vertical length of the upper variable plate 3, the width (or the number of thin plates) of the upper variable plate 3 or the angle of the V-shaped groove can be adjusted. Can be set as appropriate.

The base end portion of the lower variable plate 4 is fixed to the lower surface 17 of one end portion of the substrate 1 along the edge portion.

(Action)
The operation and usage of the magnifying glass L1 for a mobile information terminal will be described with reference to FIGS. 1 to 7.
When not in use, the magnifying glass L1 for a personal digital assistant can be folded into a substantially flat plate shape so as not to be bulky, as shown in FIG.

(1) When using the magnifying glass L1 for a mobile information terminal, first, from the folded state shown in FIGS. 6 and 7, each magnet 45 of the thin plate 41b provided at the tip of the lower variable plate 4 is pressed. , Remove the magnetized state from each magnet 18 of the substrate 1 so as to release the magnetized state. Then, by bending the lower variable plate 4 to the side opposite to the resin sheet 42, each V-shaped groove 43 is closed and can be rounded with a predetermined diameter.

In the present embodiment, the lower variable plate 4 is formed into a seven-sided cylinder by aligning the thin plate 41a at the base with the thin plate 41b at the tip and magnetizing the magnets 44 and 45, and the thin plate 41a and the thin plate 4 are formed. 41b is hard to shift and its shape can be maintained.

(2) Next, each magnet 35 of the thin plate 31b provided at the tip of the upper variable plate 3 is removed from each magnet 16 at the base of the magnifying lens 2 so as to release the magnetized state. Then, by bending the upper variable plate 3 to the side opposite to the resin sheet 32, each V-shaped groove 33 is closed and can be rounded with a predetermined diameter.

In the present embodiment, the upper variable plate 3 becomes a seven-sided cylinder by aligning the thin plate 31a at the base with the thin plate 31b at the tip and magnetizing the magnets 34 and 35 to form the thin plate 31a and the thin plate. 31b is hard to shift and its shape can be maintained (see FIGS. 1 to 3).

(3) After making the upper variable plate 3 tubular, the magnifying lens 2 is raised, the support plate 13 is raised, the V-shaped groove 132 is closed and the angle is set to a predetermined angle, and the tip of the support plate 13 is set on the substrate 1. Engage with the V-shaped groove 19. As a result, the magnifying lens 2 is set at a predetermined angle with respect to the substrate 1 (see FIG. 3).

In this way, the magnifying mirror L1 for a personal digital assistant can adjust the magnifying lens 2 to an angle at the time of folding (an angle substantially parallel to the substrate 1), and engages the support leg plate 13 with the V-shaped groove 19. Therefore, the magnifying lens 2 can be adjusted to an angle at the time of use, that is, an angle substantially parallel to the screen of the leaning smartphone S described later.

(4) The magnifying glass L1 for a mobile information terminal is placed on the top plate 6 of the desk. As a result, the magnifying glass L1 for a portable information terminal is supported by a lower variable plate 4 which is a seven-sided cylinder on one end side, and is supported by a lower corner portion on the side where the spacer member 14 of the substrate 1 is provided on the other end side. (See Fig. 3).

(5) Then, the back side of the smartphone S, which is a mobile information terminal, is passed to the non-slip plate 5 and the upper variable plate 3 which is a seven-sided cylinder, and is leaned at an appropriate angle (see FIG. 3). At this time, it is preferable to lean the screen of the smartphone S (signs omitted) so as to be parallel to the angle of the magnifying lens 2 in order to make the screen display easier to see, but a slight difference in angle is allowed (FIG. 5). The angle is a little different, but it doesn't hinder you from seeing the screen).

(6) The user sits on a chair or the like on the front side (left side in FIG. 3) of the magnifying lens 2 and looks at the screen of the smartphone S through the magnifying lens 2 from a relatively high diagonally upper position, which makes it easier to see. You can see the screen (see Fig. 4). At this time, since the substrate 1 is tilted up toward the user, the user's line of sight is at right angles to or close to a right angle to the screen, making the screen easier to see (see FIG. 3).

Further, the screen of the magnifying lens 2 and the smartphone S on the other side of the magnifying lens 2 is likely to fit in the vertical viewing angle of the user. Therefore, the user can magnify and view the screen of the smartphone S without taking an unreasonable posture such as lowering his head and looking into the magnifying lens 2. The user can also operate the screen with his / her finger by turning his / her hand forward while looking at the enlarged screen.

(7) FIG. 5 shows another usage example of the magnifying glass L1 for a mobile information terminal, in which the lower variable plate 4 is not tubular but has a curved plate shape. In this embodiment, the degree of bending (curvature) of the bent portion of the lower variable plate 4 is substantially constant due to the structure in which the V-shaped grooves 43 are provided at equal intervals.

That is, the height at which the lower variable plate 4 raises the substrate 1 is almost constant, but the substrate 1 is adjusted by adjusting the position of the bent portion of the lower variable plate 4 in the front-rear direction (horizontal direction in FIG. 3). The tilt angle of can be adjusted. Specifically, the closer the bent portion is to the spacer member 14, the larger the inclination angle of the substrate 1.

(8) Further, when the magnifying glass L1 for a mobile information terminal is not used, it can be folded into a substantially flat plate by the procedure of reversing the above steps (1) to (3). In this folded state, the magnifying glass L1 for a mobile information terminal is not bulky and is easy to carry. Further, since the magnifying lens 2 can be accommodated in the accommodating space 15 surrounded by the substrate 1 and the upper variable plate 3, it is possible to prevent the magnifying lens 2 from being damaged by contact with another place.

See FIG. The parts of the magnifying glass L2 for a mobile information terminal, which is another embodiment of the present invention, similar to each part of the magnifying glass L1 for a mobile information terminal are designated by the same reference numerals in FIG. There is. Further, in the following description, the same parts will be omitted by referring to the description of the magnifying glass L1 for a mobile information terminal, and only the different parts will be described.

In the magnifying mirror L2 for a personal digital assistant, three V-shaped grooves 19a are located near one end edge (the left end portion in FIG. 8) of the upper surface 10 of the substrate 1a in parallel with the edge parallel to the lateral direction of the substrate 1a. , 19b, 19c are provided side by side in the vertical direction (short direction) with a length extending over the entire width of the substrate 1a (see the enlarged explanatory view of FIG. 8).

According to the V-shaped grooves 19a, 19b, 19c, by engaging the tip edge portion of the support leg plate 13, when using the magnifying glass L2 for a personal digital assistant, the angle of the magnifying lens 2 is set to three different angles. Can be set to. When the support leg plate 13 engages with the V-shaped groove 19a located on the leftmost side in FIG. 8, the angle of the magnifying lens 2 with respect to the substrate 1 becomes maximum.

Further, the lens fixing plate 12a to which the magnifying lens 2 is fixed has a mounting member 11 having a right-angled cross section interposed between the lens fixing plate 12a and the substrate 1 whose edges on the connecting side are cut diagonally, and the resin sheet 131 is described above. It is connected together with the support plate 13 by a resin sheet 131a continuous with the lens sheet 131a.

Then, when the support leg plate 13 is disengaged from the V-shaped grooves 19a, 19b, 19c, the support leg plate 13 is made into a straight plate shape with respect to the lens fixing plate 12a, and the magnifying lens 2 is folded, the substrate 1, the mounting member 11 and Since the lens fixing plates 12a are in close contact with each other, each of these portions and the magnifying lens 2 fit well.

In this way, the magnifying glass L2 for the portable information terminal can set the magnifying lens 2 to an angle at the time of folding (an angle substantially parallel to the substrate 1). Further, when using the magnifying glass L2 for a mobile information terminal, the magnifying lens 2 is engaged with the support leg plate 13 with any one of the V-shaped grooves 19a, 19b, 19c, and the most appropriate angle at the time of use. Can be set to.

That is, since the magnifying lens 2 can change the set angle in three stages, when the smartphone S is leaned against the upper variable plate 3, the angle of the magnifying lens 2 is adjusted to be parallel to the screen of the smartphone S. It becomes easier to adjust to an angle that is easy to see. Further, the V-shaped groove can be appropriately set to two or four or more articles in addition to the one or three articles as described above.

The means for setting the angle of the magnifying lens 2 to a desired angle during use is not limited to the above configuration, and for example, between the members at the hinge portion (not shown) which is the center of rotation of the magnifying lens 2. Various known means such as a mechanism for stopping the rotation of the magnifying lens 2 stepwisely or steplessly by utilizing the friction, locking, and engagement of the magnifying lens 2 can also be adopted.
